Descripción del Problema
Documentos escaneados pasan fácilmente los 25 MB y bloquean adjuntos.
Por Qué Ocurre
Los PDFs incrustan fuentes e imágenes a resolución completa. Los escaneos guardan cada página como imagen grande.
Solución Paso a Paso
- 1Identify whether your PDF is text-based or scanned — the strategy differs.
- 2Open a compression tool and upload the file.
- 3Choose a compression level: high quality for print, medium for email, low for web previews.
- 4Wait for processing, then compare the output size and visual quality.
- 5Download the compressed file and replace the original if the result looks right.

Consejos Adicionales
- For scans, converting to grayscale can cut size by 30–50%.
- Remove embedded fonts you do not need for the final audience.
- Split very large PDFs first, then compress each part.
- Avoid re-compressing the same PDF many times — quality degrades each pass.
Preguntas Frecuentes
Q.How small can a PDF get?
Text-heavy PDFs can drop by 60–80%; scans depend on original resolution.
Q.Does compression affect text search?
No, as long as the PDF has real text. Image-only scans require OCR to stay searchable.
Q.Will images look pixelated?
Only if you pick aggressive compression. Medium usually looks identical on screen.
Q.Is it safe to compress signed PDFs?
Compression can invalidate digital signatures. Re-sign after compressing if needed.
Conclusión
Un PDF bien comprimido carga rápido, se envía fácil y sigue viéndose profesional.
